Harmony And Symmetry Celestial Regularities Shaping Human Culture

For the SEAC conference in Graz (2018) and for the Proceedings the motto "Harmony and symmetry - celestial regularities shaping human culture" was chosen. There were at least two strong reasons for this motto: First, the connection between astronomy and human culture has an extremely long tradition, and one of its absolute high points is the astronomer Johannes Kepler, who spent his entire life searching for the relationship between the movement of heavenly lights and ideas about harmonious structures and regular bodies. Kepler started his scientific career and authored his first book, the Mysterium cosmographicum, in Graz. Kepler argued in his first publication for the twelve-fold partition of the zodiac with arguments derived from the monochord, anticipating the procedure he developed in his Harmonices mundi. Five contributions deal with Kepler, including the harmony in musical theory. The second reason was the Eggenberg Castle. This palace, built for the nobleman Hans Ulrich von Eggenberg (1568-1634), is a remarkable piece of symmetry and harmony and an outstanding example of a strong connection between astronomy and culture. Seven contributions have the topic astronomy, astrology and architecture with the emphasis on astronomical orientation, symmetry and harmony in the Middle Ages and Renaissance. The Proceedings with ten chapters and 44 contributions range besides the mentioned "Middle Ages and beyond" and Johannes Kepler from Prehistoric Times, Bronze and Iron Age, Mythology and Ethnoastronomy, Babylonian Astronomy, Greek and Roman Astronomy, Meso- and South America, Middle East and Eastern Asia and Computational Astronomy. The celestial sphere, regarded as the sky of astronomy, as well as the heaven of divine numina, from Antiquity to Copernicus and Kepler was equated with symmetry, harmony, and beauty. Until today, this has been reflected in the structure of cultural creations, from architectural objects to musical forms.

'Computational History' derives history from data and nowadays, therefore, relies on the technologies of the digital humanities. 'Computational History of Science' addresses questions of history by evaluating historical data, e.g. for tracing back copying traditions and conclude on transfer and transformation of data and knowledge. The term 'Applied Historical Astronomy', in contrast, tries to address questions of contemporary science by evaluating historical data in comparison with most recent data. This opens new possibilities, e.g. in the search for stellar transients among historical data. In the contribution by Hoffmann & Vogt we will focus on the stellar transients among all the topics mentioned above. Philipp Protte discusses the accuracy of magnitudes and positions in ancient star catalogues, Andreas Schrimpf & Frank Verbunt present an analysis of an early modern star catalogue. Victor Reijs analyses the visibility of celestial objects for naked-eye observers, and Björn Kunzmann showcases some important variable stars in the history of astronomy. Rene Hudec presents astronomical photographic archives as a valuable data source for modern astrophysics. José M. Vaquero discusses the studies on solar observations made during the last four centuries. More technical are the contributions of Georg Zotti on Stellarium and Karsten Markus-Schnabel on data-mining and data-processing technologies. Ido Yavetz & Luca Beisel are developing a digital tool of computational history of science for the simulation of pre-modern astronomical models. Gerd Graßhoff focuses more on the application of computational history with regard to Kepler's Astronomia Nova while Tim Karberg presents an analysis of the astronomical orientation of buildings in the North Sudan.

This book "Astronomy in Culture - Cultures of Astronomy" provides a cultural history of astronomy. After a keynote on the efforts to protect the dark sky as an intangible global heritage admired of all cultures under the World Heritage Convention, tangible places of astronomical heritage are described. Archaeoastronomical sites from different continents and astronomical observatories from the late Middle Ages to the 21st century are presented as cultural heritage (material culture) in Chapter 2. Chapter 3 outlines some intangible astronomical heritage of Antiquity to the Middle Ages. Astronomical observations in all cultures are the basis for time keeping and calendars all over the world. Constellations are represented as figures resembling animals or seasonal activities, and seasonal climate determines rituals and cultural festivals. Chapter 4 is devoted to some astronomical heritage presented in modern planetariums and museums representing the modern culture. A highlight is the network study of patterns stored in the planetarium software "Stellarium". Chapter 5 contains some cross-cultural comparisons involving the whole sky. Scholars from different academic backgrounds (archaeology, history of science, philology, art history, planetarium educators, computer/data science) present their studies of this traditional knowledge and how it has been transmitted and transformed over the millennia in the seven chapters of this impressive book. Dieses Buch "Astronomie in der Kultur - Kulturen der Astronomie" bietet eine Kulturgeschichte der Astronomie. Es beginnt mit den Bemühungen, den dunklen Himmel, der von allen Kulturen bewundert wird, im Rahmen der Welterbekonvention als immaterielles Erbe zu schützen. Astronomische Observatorien und archäoastronomische Stätten werden in Kapitel 2 als kulturelles Erbe (materielle Kultur) vorgestellt. Kapitel 3 bietet das immaterielle Erbe von der Antike bis zum Mittelalter. Astronomische Beobachtungen in allen Kulturen sind die Grundlage für Zeitrechnungen und Kalender auf der ganzen Welt. Sternbilder werden als Figuren dargestellt, die Tieren oder Tätigkeiten der Jahreszeiten ähneln, und das jahreszeitliche Klima bestimmt die Rituale und kulturellen Feste. Kapitel 4 ist einem Teil des astronomischen Erbes gewidmet, das in modernen Planetarien und Museen der modernen Kultur präsentiert wird. Ein Höhepunkt ist die Netzwerkstudie der Muster, die in der Planetariumssoftware "Stellarium" gespeichert sind. Kapitel 5 enthält einige kulturübergreifende Vergleiche, die den gesamten Himmel betreffen. Wissenschaftler mit unterschiedlichen akademischen Hintergründen (Archäologie, Wissenschaftsgeschichte, Philologie, Kunstgeschichte, Planetariumspädagogen, Informatik/Datenwissenschaft) stellen in den sieben Kapiteln dieses beeindruckenden Buches ihre Studien über dieses traditionelle Wissen und seine Übertragung und Veränderung im Laufe der Jahrtausende vor.

The rock sanctuary of Yazilikaya is one of the most important ritual sites of the Late Bronze Age in Turkey. Its walls are decorated with unique rock-cut reliefs: over ninety male and female deities, animals and mythical beings - more than half of all known Hittite reliefs. The sanctuary once lay on the outskirts of Hattusa, capital of the Hittite Empire, in central Anatolia. The German Archaeological Institute has been excavating here since 1931 and the rock sanctuary of Yazilikaya has been thoroughly investigated in the process. While scientific literature is plentiful, what is lacking is a "complete Yazilikaya": a comprehensively illustrated publication in English intended both for experts and the broader reading public. This book is intended to fill that gap. It offers the reader a virtual tour of the sanctuary and can also serve as a guidebook for visitors to the site. At the same time it summarizes the results of earlier excavations as well as the latest research. Lavishly illustrated with spectacular new photographs of the rock massif, it contains a detailed description of the rock chambers with the reliefs and the accompanying temple buildings. This section is followed by chapters reconstructing the history of the sanctuary and discussing its still mysterious function. Other chapters focus on the Hittites and their capital city, the discovery of the site and its research history and much more besides - with the aim of bringing the ancient monument vividly to life before the reader's eyes.

Discusses the elements of a sign, and looks at pictograms, alphabets, calligraphy, monograms, text type, numerical signs, symbols, and trademarks.

The first comprehensive book on the topic in half a century explores recent symmetry – and symmetry breaking – related discoveries, and discusses the questions and answers they raise in diverse disciplines: particle and high-energy physics, structural chemistry and the biochemistry of proteins, in genetic code study, in brain research, and also in architectural structures, and business decision making, to mention only a few examples.
